[1] Interpreter officers are used extensively in multinational operations in which two or more countries that do not share a common language are undertaking a joint operation, or expeditionary missions in which the communication with the local population is crucial but limited by lack of language proficiency among the expeditionary force personnel.
[2][3] Interpreting services are provided by personnel from 223rd Military Intelligence Battalion (United States).
Because the military personnel of both countries usually lack proficiency in each other's language, a corps of interpreter officers were trained to facilitate communication.
They participate in meetings, high level conferences or day-to-day informal discussions to offer simultaneous or consecutive translation, usually between English and Korean.
The interpreter officers as a group are western oriented, for the qualification exam requires considerable level of fluency in English and Korean as mandatory languages.
